hot rolled 09cupcrni-a hot rolled plate production line

The hot rolled 09cupcrni-a, medium and heavy steel plate can be processed for secondary processing. If the medium and heavy steel plates are not used later, the factory can process it into other plates, which will not waste resources and save cost. The overall market situation of hot rolled 09cupcrni-a, medium and heavy steel plate is unstable, and the price changes every day. If the overall price rises, you can first observe for a period of time to find out why it has risen, and you can wait until the best price to buy.

ASTM Corten B steel is a hot-rolled structural steel product with better atmospheric corrosion resistance under Technical delivery conditions. ASTM Corten B steel conforms to ASTM standard, with yield strength of 355MPa and 345mpa, and the hot rolled 09cupcrni-a yield strength depends on the thickness. The tensile strength of ASTM Corten B steel is 470-630 MPa.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in hot rolled 09cupcrni-a etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

According to the economic development trend in Asia and the economic development of China, India, Japan and ASEAN, it is estimated that the steel consumption in Asia will be 1228 million tons in 2019, with a year-on-year growth of 6.6%; the hot rolled 09cupcrni-a steel demand in Asia in 2020 is predicted to be 1.241 billion tons, with a year-on-year growth of 1.1%. According to the hot rolled 09cupcrni-a economic development of Europe, it is estimated that the steel consumption in Europe will be 202 million tons in 2019, with a year-on-year decrease of 3.3%; the steel demand in Europe in 2020 is predicted to be 205 million tons, with a year-on-year growth of 1.5%.
